Summary

A fence stacked atop a retaining wall in Yakima's urban area can't exceed ten feet total height, measured from the lower grade, under the zoning code's site design standards.

Fence height in combination with a retaining wall: no combination of a fence and retaining wall shall exceed a height of ten feet, measured from the lower elevation, except existing retaining walls at the time of the passage of this title will be allowed a three-and-one-half-foot fence above the retaining wall.

H. Access Required. All new development shall have a minimum of twenty feet of lot frontage upon a public road or be served by an access easement at least twenty feet in width. The purpose of this standard is to provide for vehicular access to all new development; provided, the construction of single-family and two-family dwellings on existing legally established lots is exempt from the requirements of this section.

I. Recreational Screen. A recreational screen is a protective device for recreational purposes designed to keep recreational equipment within or outside of a designated area. Such uses are typically associated with schools, parks, golf courses, swimming pools, ballfields, and playgrounds. The specific standard for screen height in Table 5-1 does not apply to recreational screening as established by this title. The height and materials for screens will be evaluated by the administrative official based on the need, safety requirements, and relationship to residential and commercial properties and streets.

Full Breakdown

YMC § 15.05.020(G)(6) caps the combined height of a fence sitting atop a retaining wall at ten feet, measured from the lower elevation, in the Yakima Urban Area Zoning Ordinance's residential, commercial and industrial districts alike. Retaining walls built before the title's adoption get a narrower allowance: only a three-and-one-half-foot fence above them. Separately, YMC § 15.09.210 requires any retaining-wall material not customarily used for that purpose to be certified by a professional engineer before it can be built.

Violations & Fines

A fence-and-retaining-wall combination over the ten-foot cap, or use of uncertified nonstandard wall material, is a zoning code violation subject to a correction or removal order from the city's community development department.

Frequently Asked Questions

How tall can a Yakima retaining wall and fence be together?
No more than ten feet total, measured from the lower elevation, under YMC § 15.05.020(G)(6), unless the wall predates the title, which allows a smaller add-on fence.
Does a Yakima retaining wall need engineering sign-off?
Only if built from material not customarily used for retaining walls; YMC § 15.09.210 then requires certification by a professional engineer.
